PRECAUTIONS FOR TRAVELING ON SLOPES
WARNING: Avoid possible injury from traveling
on slopes. Tipping over or skidding down of the
machine may result. Thoroughly read and under-
stand precautions below and be sure to travel at
slow speed on slopes. Never attempt to travel on
slopes with the bucket loaded or any load sus-
pended by the bucket.
•
Never attempt to ascend or descend 30 degrees or
steeper slopes.
•
Be sure to fasten the seat belt.
•
Keep the bucket pointed in the direction of travel, ap-
proximately 0.5 to 1.0 m (1
′
8
″
to 3
′
3
″
) above the
ground. If the machine starts to skid or becomes un-
stable, lower the bucket immediately.
•
Driving across the face of a slope or steering on a
slope may cause the machine to skid or turnover. If
the direction must be changed, move the machine to
level ground, then, change the direction to ensure
safe operation.
•
Avoid swinging the upperstructure on slopes. Never
attempt to swing the upperstructure downhill. The
machine may tip over. If swinging uphill is unavoidable,
carefully operate the upperstructure and boom at slow
speed.
•
If the engine stalls on a slope, immediately lower the
bucket to the ground. Return the control levers to
neutral. Then, restart the engine.
•
Be sure to thoroughly warm up the machine before
ascending steep slopes. If hydraulic oil has not
warmed up sufficiently, sufficient performance may not
be obtained.
•
Turn the travel mode switch to the slow mode position
on level ground before traveling down a slope. Never
operate the travel mode switch while descending a
slope. Failure to do so may possibly result in causing
the machine to slip.
•
When descending steep slopes, avoid quick accelera-
tion and deceleration in the fast travel mode. Damage
to the travel motors may result.
